Given that rayon wicks better, can supply liquid at a higher rate, if anything you may be able to run at higher temperatures. Another thing about rayon wick is that many people report increased "nic hit" and lower the nicotine content of their liquids to avoid the "buzz". The same is true of flavor, many report an increase in flavor compared to other wicks.
I've been using rayon wick for about eight months now. I use it exclusively and when I do try a silica wicked coil it tastes muted and quite different than a rayon wick with the same liquid. To me, the vapor from rayon wick almost has a texture when compared to other wicking materials that makes it a much more satisfying vape. These are my personal observations and preferences, your mileage may vary.
